Starmap models were apparently inserted in the game files at one point or another. They can be used with cameras to get a pretty nice view of the planets. There also a broodlord portait in here for additional concept ideas.
Note: If you havent explored the game models yet, the actual planets are teeny tiny, smaller than a zergling with a huge hemisphere backdrop for stars and a flat square for detailed backdrops. I also didnt take the time for the views to be perfect, just enough so that it fills up the screen.
Another note: With this method, one could make a psuedo-starmap with these models placed somewhere secluded in a corner and the use of dialogs. You could also get screen-sized portaits for anything you might desire, like a story or hero selection. (flip through faces until you reach the hero you want to use, or something like that.
- Updated with Monlyth which was quite odd, it has an duplicate directly behind it which cannot be seen when looked at with the intended lighting
